Manchester City full-back Oleksandr Zinchenko has sustained a knee injury, the Premier League champions have confirmed.
A timeframe has not been placed on when the Ukraine international might return to action, with City announcing ahead of Tuesday s Champions League match against Atalanta that he will be assessed over the coming days to determine the extent of the problem .
Everyone at City wishes Oleks a speedy recovery, the statement added.
There will be fears Zinchenko is the latest City player to fall victim to a serious knee problem, with Leroy Sane and Aymeric Laporte currently recuperating following surgery during the opening weeks of this season.
Zinchenko s own opportunity to establish himself as a reliable option at left-back for Pep Guardiola came after Benjamin Mendy underwent knee operations in each of the past two seasons, while Ilkay Gundogan sat out the majority of 2016-17 with a ruptured cruciate ligament.
After impressing in Mendy s absence last term as City won an unprecedented domestic treble in England, Zinchenko was rewarded with a contract extension running until the end of the 2023-24 campaign.
Mendy has returned to fitness, while Guardiola bolstered his options at left-back by re-signing City youth-team graduate Angelino from PSV during the close season.
